[ ABOUT CARTSTRINGS ]

Specialists,
Not Generalists

We founded CartStrings on a single premise: Mastery requires focus.

Modern e-commerce email is no longer just about sending newsletters. It is a complex ecosystem of data, behavioral logic, and retention strategy. To get it right, you can't be a generalist. You have to be an engineer.

We chose to do one thing—Email Marketing for E-commerce—so we could be the absolute best in the world at it

[ Our Founder ]

Meilech Biller

Founded in 2023

Meilech built CartStrings to solve the biggest problem in the agency world: The Bait-and-Switch.

Most agencies sell you the CEO, then hand your account to a junior manager. That doesn't happen here. Meilech is an operator, not a figurehead. He personally oversees every client relationship, ensuring the strategy you signed up for is exactly what is delivered.

No "B-Team." No middlemen. Just direct access to the expert you hired.
